The Xcode project file seems to be messy.
I implement App Group detection by entitlement in LCSharedUtils.m, using the function getLCEntitlementXML() from LCMachOUtils.
So I changed the Target Membership of LCMachOUtils.m to LiveContainerSwiftUI and LiveContainerShared .
That's the change I made to the project file.

Thank you for your contribution! That looks good, I'll take a closer look later. But could you please revert your changes to the pbxproj file except the file move? We already have a Global.xcconfig to customize your team id. Also, can you cache the app group in UserDefaults so we don't have to analyze the executable at every launch, which also allows us to move these files back?

Okay. I’ll make a commit later.

Also, can you cache the app group in UserDefaults so we don't have to analyze the executable at every launch,

Sure. I’ll cache app group in App’s UserDefaults. But if the install method is Unknown, it still analyze at every launch.

which also allows us to move these files back?

As I used function in LCMachOUtils.m, which only build for LiveContainerSwiftUI target. So I must add the Target Membership to build for LiveContainerShared as well unless not getting link error. Thus I think the file move cannot be optimized until using without LCMachOUtils.m.

I mean what I suppose is that the app group is cached to UserDefaults when the ADP cert is imported, so we don't need to call getLCEntitlementXML() in LiveContainerShared. As for LiveProcess, we can pass app group id as a parameter when calling beginExtensionRequestWithInputItems.

Hi! I've reverted the changes to the pbxproj file except for the target membership modification.
Also, I cache the App Group as LCAppGroupID after the cert is imported.

So it reduces the number of calls to getLCEntitlementXML().
However, this function is still needed in LiveContainerShared for now to detect the ADP store type — so the pbxproj file does include the change related to target membership.

As for LiveProcess, we can pass app group id as a parameter when calling beginExtensionRequestWithInputItems.

Sorry, I’m not familiar with LiveProcess, so the changes related to it will need to be handled by you~ QAQ
